Why Ryan Reynolds Is (Almost) the Perfect New Dad

He's absurdly handsome, was the best thing about Green Lantern, and looks killer in a suit. Is there anything Ryan Reynolds can't do?

As it turns out, there is: The man can't breastfeed his baby to save his life.

The new dad -- wife Blake Lively gave birth to a daughter over the holidays -- jokingly fessed up about his shortcoming while promoting his new movie, Mississippi Grind, at Sundance. "I gotta jump in and do all those sorts of things," he told People.com. "I mean, I've even tried breastfeeding.

"It's frustrating for the baby and frankly, disturbing for me...not well is the answer," he quipped.

Obvious supply issues aside, it sounds like the new parents are settling into parenthood quite nicely and Reynolds is (naturally) killing it as a hands-on dad. He called parenthood "amazing" and said their baby had him wrapped around her finger "well before she was even born." (Well done, kiddo!)

Of course, that doesn't mean People's Sexiest Man Alive 2010 has been spared the most classic new parent affliction: sleep deprivation. During the press junket, he spoke in equal measures about his joy over being a new parent and his utter exhaustion after long nights on daddy duty. "It's amazing how you can be so happy and then so exhausted in the same moment. It's like cocaine without the dark alleys of shame," he told USA Today. (P.S. Are you this eloquent when you're sleep deprived? Yeah, me neither.)
